ok 7950 gx2... for what you paid for it.. and how much it kicks @$$ on all current games (reviews and specs i've read) keep your current card... it's definitly not worth the price... unless you're the type of person that can afford to throw 20 dollar bills into the wishing well instead of quarters.... and in that case... send me a 20 dollar bill and i'll work for you for 2 hours (not sexually, unless you're a hot FEMALE)
... because i'm poor. haha. anyway, WAIT! according to all the specs right now, the only good way to go is if you have a terrible card, and you're upgrading to a 7900gs or an x 1900 pr a x19650... if you have the psu to support them that is... your card actually is pretty rockin as of now... I'd suggest chilling out and waiting a while. even if you're the type of dude who wants to max out all the features (anti aliasing, anistropic filtering, etc, etc.) 8800's are not as good as they claim to be... sure, for joe bob like me who has a crappy card, the next gen 8x's seem ok, the 88's seem awesome... but from where you're sitting on the 7950... i wouldn't touch an 8800 until you find a game that either drops below 20fps (other than NWN 2) , or you have a butt load of money to spend on a top of the line card like the 8800gtx ultra.... even then... it's a waste of money, especially if you keep up with the times...
point being... if you can afford to upgrade a 7950 gx2... send me your card... i'll send you 50 bones (cuz that's all i got) toward your 8800...
but i still don't advise it, (even though i'd be making out on the deal)...
and just to make that analogy clear... you spent a butt load of money on the 7950gx2... and it's a good card.... i wouldn't spend money on anything else right now... i'd wait untill upgrading actually makes a difference (other than dx10.....dx10 is sooo gay)
